• Exchange SBS 2003 server stopped receiving mail over the weekend, senders getting "Relay access deni

  - by Charlie W.

  Firstly, I should say that I know my way around Windows very well, I don't really know the first thing about Exchange. I am trying to support a user that is running an SBS2003 Server with Exchange. Over the weekend, everyone sending something to any of his addresses gets an error message like the following: Delivery to the following recipient failed permanently: [email protected] Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 554 554 5.7.1 <[email protected]>: Relay access denied (state 14). ----- Original message ----- Received: by 10.114.18.7 with SMTP id 7mr5572745war.127.1275423472120; Tue, 01 Jun 2010 13:17:52 -0700 (PDT) MIME-Version: 1.0 Sender: [email protected] Received: by 10.143.10.15 with HTTP; Tue, 1 Jun 2010 13:17:32 -0700 (PDT) From: My Name <[email protected]> Date: Tue, 1 Jun 2010 15:17:32 -0500 X-Google-Sender-Auth: XiPrP8Em_6Eb94EH9m84nJVGvCY Message-ID: <[email protected]> Subject: TEST To: Client <[email protected]> Content-Type: multipart/alternative; boundary=001636b1484ffe72470487fdaa5b There are a host of errors in the Application log, but nothing that leaps out at me as being obvious. But then again, I don't really know what I'm looking for. Any help would be greatly appreciated.

• DVD drive won't work after installing software

  - by Dan

  DVD drive was already region-free but for some reason would not play a certain DVD as it was the "wrong region". This is the first time I've played a DVD on the drive, but I've imported a lot of CDs before and they always worked fine, even CDs bought from the USA (I live in the UK). To get around this, I downloaded a piece of software called "DVD Region Killer". (Clicking the link won't start the download, so go ahead and check it.) After this, the drive isn't recognised. It won't show up in "My Computer", and when I insert a disc it will start to whir but not take action, i.e. iTunes won't recognise that I have put a CD in. In the Device Manager, the drive shows up with a caution-sign. The device status reads: Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19) Disabling, uninstalling and reinstalling does not help. Clearly the software download is the issue, but it is difficult to remove. The only files I can find in Program Files are: C:\Program Files (x86)\Elaborate Bytes\DVD Region Killer which contains a changelog and a HTML document which has no info on uninstalling. It doesn't show up on "Add or Remove Programs", or even as a background process when I press ctrl-alt-del. Apparently it has no interface as such, and can be accessed by an icon in the system tray, (see review in link) but I don't see the icon. If it helps to know, I have a Dell Inspiron running Windows 8 64-bit, and the model of the DVD drive is: MATSHITA DVD+-RW UJ8C2 Thanks in advance.

• Five stars of open data - example and review

  - by Joe

  (there may be a more suited SE site for this question so feel free to shift) I have some data I'd like to make open to the public - It's synatesis of some related data retrived from freedom of infomation requests over the last year. The data itself is at http://www.cs.rhul.ac.uk/home/joseph/domesday/Domesday-Scotland.csv or for fans of Excel, at http://www.cs.rhul.ac.uk/home/joseph/domesday/Domesday-Scotland.xlsx . It's no more than a table with about five columns. I'd like to make this properly open data, so I was looking at the 5 star deployment scheme for Open Data. Much of which is fine but I'm confused towards the end and I could do with an explenation from people who know the answers. So to get achieve the star levels I need: "make your stuff available on the Web (whatever format) under an open license" trival - all I have to do is put the notes up on the page that will give the provance of the data. "make it available as structured data (e.g., Excel instead of image scan of a table)"… done… "use non-proprietary formats (e.g., CSV instead of Excel)" - done… "use URIs to identify things, so that people can point at your stuff" - this is where I start to get a bit hazy - does this mean there should be an URI for every line in the table? "link your data to other data to provide context" - this isn't massively clear to me - does this mean to give the provence of the data? One column of the data I've put out is a link to where the data came from - is that the sort of thing we're looking at? Any and all information and answers welcome… EDIT - or if anyone wants to recommend a place SE or other place to ask the question - that would be cool...

• Prevent nginx from redirecting traffic from https to http when used as a reverse proxy

  - by Chris Pratt

  Here's my abbreviated nginx vhost conf: upstream gunicorn { server 127.0.0.1:8080 fail_timeout=0; } server { listen 80; listen 443 ssl; server_name domain.com ~^.+\.domain\.com$; location / { try_files $uri @proxy; } location @proxy { proxy_pass_header Server; proxy_redirect off; proxy_set_header Host $http_host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto https; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Scheme $scheme; proxy_connect_timeout 10; proxy_read_timeout 120; proxy_pass http://gunicorn; } } The same server needs to serve both HTTP and HTTPS, however, when the upstream issues a redirect (for instance, after a form is processed), all HTTPS requests are redirected to HTTP. The only thing I have found that will correct this issue is changing proxy_redirect to the following: proxy_redirect http:// https://; That works wonderfully for requests coming from HTTPS, but if a redirect is issued over HTTP it also redirects that to HTTPS, which is a problem. Out of desperation, I tried: if ($scheme = 'https') { proxy_redirect http:// https://; } But nginx complains that proxy_redirect isn't allowed here. The only other option I can think of is to define the two servers separately and set proxy_redirect only on the SSL one, but then I would have duplicate the rest of the conf (there's a lot in the server directive that I omitted for simplicity sake). I know I could also use an include directive to factor out the redundancy, but I really want to keep just one conf file without any dependencies. So, first, is there something I'm missing that will negate the problem entirely? Or, second, if not, is there any other way (besides including an external file) to factor out the redundant config information so that I can separate out the HTTP and HTTPS versions of the server config?

• how to block spam email using Microsoft Outlook 2011 (Mac)?

  - by tim8691

  I'm using Microsoft Outlook 2011 for Mac and I'm getting so much spam I'm not sure how to control it. In the past, I always applied "Block Sender" and "Mark as Junk" to any spam email messages I received. This doesn't seem to be enough nowadays. Then I've started using Tools Rules to create rules based on subject, but the same spammer keeps changing subject lines, so this isn't working. I've been tracking the IP addresses they also seem to be changing with each email. Is there any key information I can use in the email to apply a rule to successfully place these spam emails in the junk folder? I'm using a "Low" level of junk email protection. The next higher level, "high", says it may eliminate valid emails, so I prefer not to use this option. There's maybe one or two spammers sending me emails, but the volume is very high now. I'm getting a variation of the following facebook email spam: Hi, Here's some activity you have missed. No matter how far away you are from friends and family, we can help you stay connected. Other people have asked to be your friend. Accept this invitation to see your previous friend requests Some variations on the subject line they've used include: Account Info Change Account Sender Mail Pending ticket notification Pending ticket status Support Center Support med center Pending Notification Reminder: Pending Notification How do people address this? Can it be done within Outlook or is it better to get a third party commercial software to plug-in or otherwise manage it? If so, why would the third party be better than Outlook's internal tools (e.g. what does it look for in the incoming email that Outlook doesn't look at)?

• How do I reinitialise a failed RAID 5 drive using terminal on Ubuntu Server

  - by Stephen

  I've currently put together a new system and part of that has been creating a software RAID 5 using 'mdadm' in Ubuntu Server. I successfully got to the point where I create the array using: sudo mdadm --create --verbose /dev/md0 --level=5 --raid-devices=4 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 I left it to do its thing overnight then used the following command to check on it: watch cat /proc/mdstat To which the following was returned: Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md0 : active raid5 sdd1[4](S) sdc1[2] sdb1[1] sda1[0](F) 5860535808 blocks super 1.2 level 5, 512k chunk, algorithm 2 [4/2] [_UU_] unused devices: <none> It appears that one has failed (and I'm not too savvy with why another is a spare). So, just to be sure that something else isn't amiss I wanted to try and re-engage the failed drive. Can someone explain how I can do that and what I should do with the spare (if anything). And also how do I know when synchronisation is complete? The tutorial I used to get this far is located here: http://sonniesedge.co.uk/2009/06/13/software-raid-5-on-ubuntu-904/ Many thanks! p.s.

• How to create a static IP on Windows Server 2008 R2 so I can access the server remotely

  - by Aesir

  I have just purchased a HP Proliant N40L which I am intending to use as a NAS, learning tool and just in general something to mess around with. As a student via the Microsoft dreamspark program I can get a free copy of Windows Server 2008 R2 which I am using as the OS. So that I can remote to the box from outside of my local network and so that I can stream media from it to my PS3, I have read that I need to create a static IP for the server and use port forwarding to forward to this IP so I can remote in. Is this correct? I am not really sure how to do this and if I need to make these changes on my router configuration, on the OS or both. I am a novice when it comes to networking however most resources for Windows server 2008 R2 seem to assume a fair amount of experience already. I realise that using this particular OS may seem like overkill for what I currently wish to do with it (stream content to other devices and backup) but as I can get a copy for free it seems sensible. Edit: From reading answers posted I feel I should give more information. I have now tried to add a static IP address using my router configuration settings. I have used the getmac command to get the mac address of the server. My ISP is Virgin Media and I have gone to the LAN IP section and I have added an IP address to the DHCP Reservation Lease Info. I can now use remote desktop connection internally to remote to the server (so I am assuming assigning this IP has worked). How do I configure this on the OS as well? I am also unsure on how I would remote to this machine outside of my local network?

  I have a server I am running: Ubuntu 10.04 php 5.3.5 (fpm) Nginx I have installed postfix, and set it to loopback-only (only need to send) The problem is it is not sending. if i issue (at command line): echo "testing local delivery" | mail -s "test email to localhost" [email protected] I get the email no problem, but through PHP it does not arrive.

• Add single sign-on into existing web app

  - by EvilDr

  Apologies if this isn't the best site, I've search for an answer but can't find anything quite right. I don't actually now the correct terminology I should be using here, so any pointers will be appreciated. I have a web application that accessed by many different users across different organisations. Access is provided by each user having a unique username/password which is stored in SQL (database fields are customerID, userID, username). Some organisations are now asking if we can change this to allow "Active Directory single sign-on" so that users don't need to remember yet another set of login details. From research I can see how this is achieved using OpenAuth and Google (etc), but I know hardly anything about AD and can't find much information on this (again I'm sure it helps when you know the terminology). Is this request even possible to achieve, given that most users will be from different (and unrelated) organisations? I saw on a Microsoft Build video not long ago that there is some kind of replication service for AD to allow Cloud authentication. Is this what I should be aiming for?

• What could cause random files being downloaded without permission?

  - by Dustin

  I have been having issues lately with a certain directory. It seems someone is placing files into it, or something of that sort, and any attempt to delete them is successful, HOWEVER they reappear over time (maybe not the exact same ones, but random files). I will provide you the information I can and several pictures of my problem: sandbox.mys4l.com/visual/files/b1.jpg Files like this have been appearing in my /visual/ folder, and I have no clue where they are coming from. sandbox.mys4l.com/visual/files/b2.jpg This is what is inside on of those weird files, it appears to be nothing problematic. sandbox.mys4l.com/visual/files/b4.jpg As you can see, in the time it took me to take the first picture, more odd files showed up. These log files are also being uploaded to this directory, and I know I didn't put them there. sandbox.mys4l.com/visual/files/b7.jpg This inside one of these mysterious .log files, I'm not sure what it's all about. These files only appear to be going into this specific area, and I'm not sure of their origin, only that they will not go away. I have done a full system scan at least twice with an up-to-date virus scan, and have looked for an unknown script which may be writing them there. Nothing has come up, so I come to you guys as I hear this is the best place to find answers. Hope this problem has a solution!

• USPTO site asks for Quicktime Plug-in which I already have installed. Why?

  - by Kensai

  Whenever I try to watch the images of a patent in the USPTO site (example) using Firefox, the browser asks me to download the latest Quicktime, manually. This is totally strange because I already HAVE the latest plug-in (it even appears on my Firefox add-ons list). In the past I have only been able to see patent images using Safari. But never with Firefox. Is it a USPTO problem or a Mozilla one? Is there a way to fix the problem? edit: I can't see TIFF images neither with Internet Explorer (both 32-bit and 64-bit versions) nor with Chrome. All these browsers don't know how to open embedded TIFF images because they don't recognize the installed Quicktime plugin. A USPTO conspiracy to promote Safari? Come to think of it, I had this problem in my old computer as well. It had a 32-bit Vista OS, now I have 64-bit Windows 7. I hate TIFF and can't find Mozilla-specific information anywhere.. Arghh, am I the only one here with this freak problem?!

• Ping and crawling not working, site still resolving

  - by Andrew Alexander

  Ok, so we're trying to figure out why the site of one of our clients isn't being crawled by Google (we've ruled out robots.txt or meta tags) When we go to the site, either IP address or domain name, the site resolves, everything works. However, Google is getting a 302 redirect (which it apparently isn't following for crawling), and when we ping the address, it times out (note, the site is still resolving in the browser throughout all of this). The site is built in ASP.Net (I assume C#) and so my thoughts were that it was an errant redirect rule, or some other sort of server side issue. We also thought that it might be due to incorrect domain pointing (but if we try to ping the IP, it doesn't work, so that sorta rules that out). We're really not sure what is causing all of these errors, or even if they have one single source. Anyone have any ideas what could be going on? Do you need any more information? To boil it down in a TL; dr: * Site resolving in browser, both IP and domain name. No problems here. * Site not being crawled by Google (gets a 302 it doesn't seem to follow) - it is not due to robots.txt or meta tags * Ping is not working for the IP address. This is very odd, because again, the IP address seems to work fine in the browser. * Our thoughts are either redirect rule issue, domain pointing issue, or possibly some errant code - or some combination of the three

• Exchange 2003 ActiveSync problem with certificate

  - by colemanm

  We're having problems getting iPhones to sync properly with SBS 2003 Exchange. When you add a new Exchange ActiveSync account on an iPhone and enter all the pertinent information, it shows a "Verifying Exchange account info" message for a minute or so, then says everything's verified and asks what you want to sync, Mail, Contacts, Calendars... so it looks like it's working. However, when you go to the Mail app and select the Exchange email account, it just shows an "Inbox" folder with nothing in it. When you try refreshing, it attempts for a second, then says "Last Updated" with a timestamp, as if it worked, but there's no mail and no error message/feedback at all. I think I've narrowed it down to some sort of certificate issue, but I'm having trouble finding out where to go from here... I ran MS's Exchange connectivity testing tool with these results: Our cert was purchased from Network Solutions, and I'd already added it to the IIS Default Website for OWA purposes. But this report makes it look like the cert is somehow problematic. I don't know what to do now... Here's a shot of the cert details, just in case:

• What is proper relationship between /etc/hosts and DNS A records for a Linux server?

  - by MountainX

  I have an Ubuntu server. It is going to be a web server with a URI of www.example.com. I have a DNS A record pointing www.example.com to the server's IP address. Let's say I pick "trinity" as the hostname for this server. I want to set up the DNS records correctly. I need reverse DNS to www.example.com, so a CNAME for www.example.com doesn't seem appropriate. Here's my question: Is it considered best practice to set up two DNS records (which in my case would likely be two A records), one for www.example.com and one for trinity.example.com, both pointing to this server's IP address? (Or, even if it is not accepted as a best practice, is it a good idea?) If so, would the following be a proper /etc/hosts file? $ cat /etc/hosts 127.0.1.1 trinity.local trinity 99.100.101.102 trinity.example.com trinity www.example.com This server is a Linode and Linode's docs seem to imply that the above approach is best (if I am reading them correctly). Here's the relevant section. I bolded the line that seems to apply here. Update /etc/hosts Next, edit your /etc/hosts file to resemble the following example, replacing "plato" with your chosen hostname, "example.com" with your system's domain name, and "12.34.56.78" with your system's IP address. As with the hostname, the domain name part of your FQDN does not necesarily need to have any relationship to websites or other services hosted on the server (although it may if you wish). As an example, you might host "www.something.com" on your server, but the system's FQDN might be "mars.somethingelse.com." File:/etc/hosts 127.0.0.1 localhost.localdomain localhost 12.34.56.78 plato.example.com plato The value you assign as your system's FQDN should have an "A" record in DNS pointing to your Linode's IP address. For more information on configuring DNS, please see our guide on configuring DNS with the Linode Manager.

• Best tool for monitoring backups, etc. and trending statstics from that data

  - by Randy Syring

  I have done some research on nagios, opennms, and zenoss but am not confident that I have found what I am looking for. The main driving force for me right now is being able to monitor backups. This includes mysql, mssql, and eventually some file system backups. We have a tool that wraps the backup process for these different systems and collects statistics. So, items like: number of databases backed up size of db backup file size of db backup file compressed time to make backup time to zip file I want to be able to A) have notifications if the jobs are not run according to schedule B) be able to set thresholds on the statistics which would trigger notifications C) I want to be able to trend and graph the statistics I am planning on sending this information to the monitoring application through an HTTP POST. Or, the monitoring application could pull it from a log file as well. However, we will have other processes with other "arbitrary" (from the monitoring system's perspective) statics that will want to monitor and trend, so flexibility is very important. The tool or tools should also be able to do general monitoring and trending of network interfaces, server load, etc. Once we get the backup monitoring in place, we will want to include those items as well. Thanks.

• Is UPS worthwhile for home equipment?

  - by Jon Skeet

  Over the years, I've had to throw away a quite a few bits of computing equipment (and the like): Several ADSL routers with odd symptoms (losing wireless connections, losing wired connections, DHCP failures, DNS symptoms etc) Two PVRs spontaneously rebooting and corrupting themselves (despite the best efforts of the community to diagnose and help) One external hard disk still claiming to function, but corrupting data One hard disk as part of a NAS raid array "going bad" (as far as the NAS was concerned) (This is in addition to various laptops and printers dying in ways unrelated to this question.) Obviously it'll be impossible to tell for sure from such a small amount of information, but might these be related to power issues? I don't currently have a UPS for any of this equipment. Everything on surge-protected gang sockets, but there's nothing to smooth a power cut. Is home UPS really viable and useful? I know there are some reasonably cheap UPSes on the market, but I don't know how useful they really are. I'm not interested in keeping my home network actually running during a power cut, but I'd like it to power down a bit more gracefully if the current situation is putting my hardware in jeopardy.

• Cannot Access Local Network Shares (Strange Schannel and lsass.exe issues)

• 553-Message filtered - HELO Name issue?

  - by g18c

  I am having major issues sending from my SBS2011 machine to Message labs server-13.tower-134.messagelabs.com #553-Message filtered. Refer to the Troubleshooting page at 553-http://www.symanteccloud.com/troubleshooting for more 553 information. (#5.7.1) ## I have changed the IP and hostnames from the below. I am not on any IP or domain blacklists. I have setup SPF (which includes mailchimp servers): v=spf1 mx a ip4:95.74.157.22/32 a:remote.mydomain.com include:servers.mcsv.net ~all I am sure i have setup my HELO names correctly under the Exchange Management console, sending a test email from the SBS server and looking at the header shows the following: X-Orig-To: [email protected] X-Originating-Ip: [95.74.157.22] Received: from [95.74.157.22] ([95.74.157.22:52194] helo=remote.mydomain.com) by smtp50.gate.ord1a.rsapps.net (envelope-from <[email protected]>) (ecelerity 2.2.3.49 r(42060/42061)) with ESMTP id 11/90-10010-E529C835; Mon, 02 Jun 2014 11:04:09 -0400 Received: from MYSBSSVR.mydomain.local ([fe80::3159:95a6:23f:1bef]) by MYSBSSVR.mydomain.local ([fe80::3159:95a6:23f:1bef%10]) with mapi id 14.01.0438.000; Mon, 2 Jun 2014 19:03:56 +0400 Is is the main helo name there OK and do i need to worry about the second Received block where the MYSBSVR.mydomain.local is mentioned? I have asked the ISP to set the reverse DNS for my IP to remote.mydomain.com but they have instead put remote.MYDOMAIN.com - would this case cause HELO lookups to classify this as not matching? Anything else I can do to find out why i am being filtered?

• SSH connection problem - allowed from LAN but not WAN

  - by Kerem Ulutas

  I tried to setup my Arch Linux installation to be an SSH host, but here is the thing: I can ssh localhost, it fails to login via public key and asks for username and password, but still able to login. When I try ssh my_wan_ip it gives ssh_exchange_identification: Connection closed by remote host error. I've read all topics about this error and none helped me. By the way, just confirmed, it gives ssh: connect to host my_dyndns_hostname port 22: Connection refused from another machine (outside of my network, it has different wan ip). I have sshd: ALL in "hosts.allow", ALL:ALL in "hosts.deny". I am able to connect to my own pc via ssh, ping my own pc, but my ssh setup seems to be the problem, it gives that annoying error when I try to ssh from wan. /etc/ssh/ssh_config /etc/ssh/sshd_config And finally, here is the debug output for both sshd and ssh: (i ran ssh command and i took output to sshd debug after that): sshd debug ssh debug I can edit my question according to your needs. Just ask for any more information needed. BTW I have no iptables running. I have one cable dsl modem connected to a asus wl-330gE wireless access point, they both have their firewall disabled. I configured NAT so port 22 is directed to the pc I'm having this trouble. Any help appreciated, thanks..

• BackupExec 2012 File System Archiving - Access is denied to Remote Agent

  - by AllisZero

  Gentlemen, I've been struggling with a Trial version of Symantec Backup Exec 2012 for about a week now. It was installed as an upgrade to our 12.5 license, and the setup completed with no issues. The reason I upgraded is solely for the File System Archiving option as I'm working to reduce the amount of live data in my servers. Backups work A-Ok and I have followed the instructions in the Admin Manual to make sure I had filled all requirements. The account BE is running under is a member of the Local administrators group as required and has been added to the test share that I'm using to evaluate the archiving function. Testing the credentials in the job setup window always works fine, and I am able to add both regular and Admin$ shares to my Archive selection. However, every time I run the Archive job, I get the following message: https://dl.dropbox.com/u/59540229/BEXec.png I've already tried to troubleshoot DNS resolution issues as suggested in the Symantec KB to no avail. The only thing I can think of, at this point, is that a trial license doesn't allow me to use the Archiving function, although that would seem silly on their part. Appreciate any assistance or information. Thanks.

• Does this exist: a standardized way of documenting a file-system structure

  - by eegg

  At work, I'm in charge of maintaining the organization of a whole lot of varied data on a standard file-system. Part of this is coming up with sensible classification (by similarity, need, read/write access, etc), but the bigger part is actually documenting it: what documents/files/media should go where, what should not be in this directory, "for something slightly different, see ../../other-dir", etc. At the moment, I've documented this using a plaintext file filing.txt in every directory I want to document. If someone is unsure what's meant to be in any directory, they read that file. This works alright, but it seems odd that I have this primitive custom solution to a problem that any maintainer of a non-trivial directory structure must experience. Every company I've known of, for example, has some kind of shared file-system where agreed terminology for categorization is important. In my experience, people just have to learn what's what by trial-and-error and experimentation. So allow me to propose a better solution, and hopefully you can tell me if it exists. Any directory on any filesystem can have a hidden plaintext file named .filing. Its contents are descriptive human language. It uses some markup like Markdown, with little more than bold, italic, and (relative) hyperlinks to other directories. Now a suitably-enabled file browser will check for a file named .filing whenever it displays a directory. If it exists, its contents are parsed and displayed in an unobtrusive pane near the directory-path widget. Any links therein can be clicked, and the user will be taken to the target directory of that link. I think that the effort of implementing such a standard would pay back many times over in usability gains. We would have, say, plugins for Nautilus, Konqueror, etc.. It could be used to display directory information in the standard file lists served by webservers. And so on. So, question: does such a thing exist? If not, why not? Do people think it's a worthwhile idea?
